On April 14, 1932, British physicists John Cockcroft and Ernest Walton achieved the unthinkable at the Cavendish Laboratory in Cambridge by successfully splitting the lithium atom. Using a pioneering particle accelerator of their own design, they triggered the first artificial nuclear disintegration, a moment that fundamentally validated Albert Einstein's theory of mass-energy equivalence. Their work earned them the 1951 Nobel Prize in Physics and established the technological blueprint for modern facilities like the Large Hadron Collider. This episode of Deep Dive explores the mechanics of that breakthrough and reflects on the legacies of country music icon Loretta Lynn, baseball's hit leader Pete Rose, and actress Sarah Michelle Gellar, all born on this transformative day in history.
